Abstract
The discussion involves the issues relating rational development of natural noble metal placers and the placer mining waste, their resource potential and basic trends in mining, processing and beneficiation. It is found that the determinants of profitable development of a technogenic object (mine waste) is its pre–restructuring aimed at generation of a new structure and at increase in value of the reserves adapted to the chosen mining and processing technologies. The author substantiates the necessity and advisability of innovative technologies for placer mining waste development based on formation of concentration zones of commercial value components in dumps. The developed ways of technology modernization for gold washing machines enable increase in recovery of gold and other valuable associate components within a single work cycle.
